## Abstract

An antenna apparatus and an image display apparatus including the same are disclosed. An antenna apparatus according to an embodiment of the present disclosure comprises a substrate, a metal mesh disposed on a portion of an upper portion of the substrate, and a protective layer disposed on the metal mesh, wherein the protective layer and the substrate are more transparent than the metal mesh. Accordingly, breakage of a metal mesh inside a transparent antenna apparatus may be reduced.
